I'm running XP on Parallels 4 for Mac, and it's working well enough, however one thing that's bothering me more and more as I go along is the way it constantly assumes every press of the command key means I want the start menu to come up. I've tried to remap it in the Parallels preferences, but all that does is allow me to create additional ways to call the start menu. Is there a setting either within XP or somewhere outside that I can set to discourage this behavior?
I had the same problem and i just disabled the windows key in xp. it might not help you but at least you get rid of the annoying pop of the window start menu:
